Meghan Markle and Prince Harry Were All About the PDA at Princess Eugenie's Royal Wedding

Endless articles have been written about the duke and duchess of Sussex's famous PDA—from smooching at polo matches to exchanging back massages at various royal engagements to famously holding hands in public before they were married—and Princess Eugenie's wedding to Jack Brooksbank was no different. Pics from the nuptials show the couple were up to their usual tricks on Friday morning, holding hands to, from, and during the wedding, hugging, and as Harper's Bazaar reported, giggling in the pews.

They weren't the only ones. It looks like Meghan and Harry's touchy-feely vibes were contagious, because Prince William and Kate Middleton (who were sitting next to them) also had a rare PDA moment: They were photographed holding hands in the pews.

While there's technically no rule against royal couples showing the public they actually like each other, Meghan and Harry's PDA often makes headlines because it's so unusual. “It is rare to see royal couples holding hands on official outings,” Myka Meier, founder and director of etiquette company Beaumont Etiquette, told People.

“Meghan and Prince Harry holding hands at a royal engagement is a refreshingly modern approach to their new role both as a couple and as representatives of the royal family,” she said, adding, "While Prince Harry and Meghan holding hands is atypical for royal engagements, it is a seemingly welcomed gesture to show unity and celebration of their engagement period. There is no protocol that says they can not show affection on official engagements, and this gesture makes them relatable and lovable to the public."
